I didn't understand anything. In the post you provided, everything is deliberately explained vaguely without going into technical details.
Autoban is when the system automatically bans without moderator participation? Right? But by what criteria? By IP match?
The forum doesn't perform regional restrictions neither district on IP but though if dictated of undergone/undergoing illegalities that're highily prohibited by the forum, there's a censor tool program that detects your activities and then automatically gets you banned.
This is what I can contribute here but expecting further or the technical factors is what I can't help out.
